Earliest footprints outside Africa discovered in Norfolk – “Scientists have discovered the earliest evidence of human footprints outside of Africa, on the Norfolk Coast in the East of England. The footprints are more than 800,000 years old and were found on the shores of Happisburgh.” – aaaand then they got washed away in the storms. (>_<)

Immediate replacement of fishing with dairying by the earliest farmers of the northeast Atlantic archipelagos [i.e. british isles] – “These new findings…unequivocally confirm rejection of marine resources by early farmers coinciding with the adoption of intensive dairy farming. This pattern of Neolithization contrasts markedly to that occurring contemporaneously in the Baltic, suggesting that geographically distinct ecological and cultural influences dictated the evolution of subsistence practices at this critical phase of European prehistory.”

The booms and busts of Neolithic Europe (and their potential impact on our DNA) – “most of the interactions between the genetically Near Eastern-like Neolithic farmers and indigenous European hunter-gatherers, including mixing, in all likelihood took place on the peripheries of the farming societies. If so, then perhaps every time there was a bust, it was the relatively more admixed, or even more hunter-gatherer-like, farmer groups from the peripheries that took advantage of the situation and moved in to grab some land in the depopulated regions? In other words, this might have been the process which led to the well-documented reemergence of hunter-gatherer-derived ancestry in the heart of Europe after the early Neolithic.” – @eurogenes.

The Fading of the Most Basal of Basal – “[T]he western and eastern Pygmy populations of the Congo rainforest seem to have diverged tens of thousands of years ago, tens of thousands of years after their divergence from the ancestors of their agriculturalist neighbors.” – from razib.

Black Death Left a Mark on Human Genome – “Genetically, the Rroma are still quite similar to the northwestern Indians, even though they have lived side by side with the Romanians for a millennium, the team found. But there were 20 genes in the Rroma and the Romanians that had changes that were not seen in the Indians’ versions of those genes, Netea and his colleagues report online today in the Proceedings of the National Academy of Sciences. These genes ‘were positively selected for in the Romanians and in the gypsies but not in the Indians,’ Netea explains. ‘It’s a very strong signal.'”

Study demonstrates evolutionary ‘fitness’ not the most important determinant of success – “By modelling populations over long timescales, the study showed that the ‘fitness’ of their traits was not the most important determinant of success. Instead, the most genetically available mutations dominated the changes in traits. The researchers found that the ‘fittest’ simply did not have time to be found, or to fix in the population over evolutionary timescales. The findings suggest that life on Earth today may not have come about by ‘survival of the fittest’, but rather by the ‘arrival of the frequent’.”

Burakumin, Paekchong, and Cagots – “Human evolution is a logarithmic curve where most of the interesting changes have happened since the advent of farming and complex societies. *Homo sapiens* was not a culmination but rather a beginning…of gene-culture co-evolution. There are many ways to study this co-evolution, but one way is to look at the different evolutionary trajectories followed by castes and their host populations.” – from peter frost.

Quick Post: L&V’s National IQs predict GMAT scores across 173 nations – “We have shown that measures of national cognitive ability predict both GMAT scores and English proficiency scores independent of rates of English usage. GMAT and English proficiency scores seem to be indexes of National (g) by way of National IQ and National ACH.” – @human varieties.

Meritocracy doesn’t work. It’s in the Left’s interest to recognise this. – “The Son Also Rises, a study of social mobility by Gregory Clark, will surprise and also alarm some people. He notes, by using surname patterns, that mobility is minimal in all societies where the data is available. Even, for example, in the Nordic paradise of Sweden. He says: ‘In all societies, what seems to matter is just who your parents are. At the extreme, we see in modern Sweden an extensive system of public education and social support. Yet underlying mobility rates are no higher in modern Sweden than in pre-industrial Sweden or medieval England.’ He also notes that even in revolutionary societies, such as in Communist China, people with aristocratic surnames also turn up at the top, showing that once again Darwin trumps Marx.” – from ed west. – see also: Everyone likes the idea of equal opportunity. This economist thinks it’s a fantasy.

Males and females differ in specific brain structures – “Reviewing over 20 years of neuroscience research into sex differences in brain structure, researchers have conducted the first meta-analysis of the evidence. The team performed a quantitative review of the brain imaging literature testing overall sex differences in total and regional brain volumes. They found that males on average have larger total brain volumes than women (by 8 to 13 percent). Looking more closely, the researchers found differences in volume between the sexes were located in several regions. These included parts of the limbic system, and the language system.”

How much do sex differences matter in sports? – “Thanks in large part to testosterone, men are generally heavier and taller than women. They have longer limbs relative to their height, bigger hearts and lungs, less fat, denser bones, more oxygen-carrying red blood cells, heavier skeletons that support more muscle — 80 percent more in the upper body, on average, which is about the difference between male and female gorillas — and narrower hips that make for more efficient running and decrease the chance of injury. But since these differences generally don’t appear until puberty, boys’ and girls’ records in track tend to be identical before age 10. There’s scant biological reason to separate young boys and girls in competitions.” – from david epstein.

Male infanticide leads to social monogamy in primates – “The origin of social monogamy in primates is best explained by long lactation periods caused by altriciality, making primate infants particularly vulnerable to infanticidal males. We show that biparental care shortens relative lactation length, thereby reducing infanticide risk and increasing reproductive rates. These phylogenetic analyses support a key role for infanticide in the social evolution of primates, and potentially, humans.” – h/t heartiste!

23andMe Couples Correlated – “For Valentine’s Day, we analyzed data from 15,298 real-world couples who had children together and found that people paired with others who were more like themselves than they were different.”

Ethnic diversity’s ‘inconvenient truths’ – “[W]hen the Vancouver Foundation recently conducted a massive survey of Metro Vancouver residents, researchers discovered most people in this West Coast city feel unusually high levels of loneliness and lack of friends…. The Vancouver Foundation survey of 3,800 diverse Metro residents confirmed Putnam’s results. It found one in four Metro residents feels alone more often than they would like, one-third consider Vancouver a difficult place to make friends, most don’t socialize with their neighbours, half don’t volunteer and most feel that, while diversity is generally a good thing, they prefer to be with members of their own ethnic group.” – h/t mike anissimov!

Rainforests in Far East shaped by humans for the last 11,000 years – “New research shows that the tropical forests of South East Asia have been shaped by humans for the last 11,000 years. The rain forests of Borneo, Sumatra, Java, Thailand and Vietnam were previously thought to have been largely unaffected by humans, but the latest research suggests otherwise.”

How HBD Will Make you a Better Person – “[F]orbidden knowledge does not result in genocide. The problem with this view is that genocide has been the norm throughout human history — that is, until very recently. On a historical timeline, our recent scientific knowledge of racial differences actually negatively correlates with the historic trend of genocide.” – @occam’s razor.

Robots and HBD denialism – “The coming robot revolution will make the labor of people below a certain IQ totally worthless. This is an event never before experienced by humanity.” – from the lion of the blogosphere.

Church Making Strides Preserving African Family Histories – “Genealogy experts are experiencing a race against time in Sub-Saharan Africa; an area that spans 36 countries. There is an urgency to collect oral interviews of African genealogy because family historians are aging and some are dying before those histories can be recorded.” – h/t t.greer!

Genomewide diversity in the Levant (Haber et al. 2013) – “Our results show recent genetic stratifications in the Levant are driven by the religious affiliations of the populations within the region…. Levant populations today fall into two main groups: one sharing more genetic characteristics with modern-day Europeans and Central Asians, and the other with closer genetic affinities to other Middle Easterners and Africans.” – @dienekes’.

Feet on the Autism Spectrum – “Psychotherapist Cary Terra works with adults with autism spectrum disorder…. Over many years, she’s noticed what she calls an ‘unmistakable trend’: that her patients have a tendency to sit with their feet stacked.” – *hbd chick looks down* – oops!

i should just move the linkfests to mondays … get it over with. (~_^) (then at some point i’d prolly switch to publishing them on wednesdays or thursdays … and eventually, someday, they’d migrate all the way back to sundays again!)

Does being fat make you more jolly? – “The FTO gene makes a protein associated with obesity and fat mass…. [H]aving one copy of this mutant in your genome decreases the risk of depression by 8 per cent; two copies doubles that dip…. Based on its prevalence among ethnic groups, it should prevent 6.7 per cent of the cases of depression that would otherwise afflict Africans, 5.3 per cent of cases in Europeans, and 2.2 per cent in Chinese.”

Mitochondrial DNA in Ancient Human Populations of Europe (der Sarkissian 2011) – “This work presents direct evidence that Mesolithic eastern Europeans belonged to the same Palaeolithic/Mesolithic genetic background as central and northern Europeans. It was also shown that prehistoric eastern Europeans were the recipients of multiple migrations from the East in prehistory that had not been previously detected and/or timed on the basis of modern mtDNA data. Ancient DNA also provided insights in the genetic history of European genetic outliers; the Saami, whose ancestral population still remain unidentified, and the Sardinians, whose genetic differentiation is proposed to be the result of mating isolation since at least the Bronze Age.” – @dienekes’.
